## What it is
An Objective-C category library extending NSDate with practical, real-world date calculations and utilities. It is now superseded by the author's SwiftDates library, which offers expanded and updated APIs.

## Use cases
- calculate date differences in objective-c
- get start of week or month from nsdate
- compare dates ignoring time components
- check if a date is today or tomorrow
- add days or months to an nsdate
- practical date math for ios apps

## When to choose
- maintaining a legacy Objective-C codebase that already uses it
- you need simple NSDate category helpers and cannot adopt Swift

## When to avoid
- starting a new Swift project - use SwiftDates instead
- you need actively maintained date utilities
- your project requires a permissive license - this repo has no license file

## Facets
- artifact type: library
- maturity: abandoned
- function: date-time
- domain: developer-tools, cross-platform
- platform: -
- tags: objective-c, nsdate, date-utilities, cocoa, superseded, macos, ios
